The input material for this process is a precisely prepared forged blank, which undergoes a sequence of high-precision machining operations such as turning, grinding, and induction hardening to achieve the required roller dimensions and surface finish. These operations are performed using advanced machinery including CNC Turning Centers, Cylindrical Grinding Machines, and Induction Hardening Equipment to ensure superior accuracy, consistency, and surface integrity. The critical parameters for this process include the roller diameter and surface hardness, both of which are maintained within a strict tolerance of ±0.02 mm and specified hardness range as per the drawing requirements. Additionally, to meet customer-specific quality standards, corrosion prevention measures are implemented through the application of protective oil coating, ensuring the rollers remain defect-free during storage and transportation.
